How to Run a TikTok Competition in Australia: Complete Guide

Why Run a Competition on TikTok?

TikTok is Australia's fastest-growing social platform, with over 8.5 million active users spending an average of 1.5 hours a day on the app. Unlike Facebook and Instagram, TikTok's algorithm is content-first: your competition video can reach millions regardless of your follower count. If your target market includes Australians under 35, TikTok is where they're spending their attention.

Content-First Algorithm

TikTok shows content to people based on what they watch, not who they follow. A brand-new account with zero followers can get a competition video in front of hundreds of thousands of Australians if the content is engaging. No other platform offers this level of organic reach for new accounts.

Built for Participation

TikTok's Duet, Stitch, and sound features are designed for users to build on each other's content. Competition hashtag challenges tap directly into this participatory culture, turning entrants into content creators who amplify your brand to their own followers.

Unmatched Engagement

Australians spend an average of 26 minutes per TikTok session — significantly more than any other social platform. This deep engagement means users are more likely to watch your competition video in full, read your caption, and take action.

Younger Demographics

The 18–24 age group dominates TikTok in Australia. If you're a brand targeting Gen Z and younger millennials — fashion, beauty, food, tech, entertainment, fitness — TikTok is your primary channel for reaching them authentically.

Australian under-16 ban: From December 2025, Australia has legally banned social media use for under-16s. TikTok must remove or block under-16 accounts. This means your competition audience on TikTok in Australia is 16+ (or 18+ if you set that in your T&Cs). Factor this into your eligibility requirements.

TikTok's Promotion Policies

TikTok has its own set of promotion rules, separate from Meta's. While less prescriptive in some areas, TikTok has introduced stricter policies around commercial disclosure and giveaways. These apply on top of all Australian legal requirements.

What You CAN Do

Ask users to comment on a video to enter
Ask users to follow your account to enter
Ask users to create a video using your hashtag
Ask users to Duet or Stitch your video
Use a branded sound for entries
Run from a Business or Creator account
Link to an external landing page for entries
Encourage sharing and saving

What You CANNOT Do

Offer cash or gift cards via TikTok Shop giveaways
Run promotions that mislead users about prizes or odds
Fail to disclose commercial content (mandatory since 2026)
Use gamification mechanics in TikTok Shop
Target users under 16 in Australia
Imply TikTok sponsors your competition
Run live giveaways without 1,000+ followers
Skip stating terms, eligibility, and prize details

Commercial content disclosure (2026): TikTok now requires all promotional posts to be clearly labelled using TikTok's built-in disclosure tools. Any competition video that promotes your brand, product, or service must include this disclosure. Failing to label promotional content can result in video removal and account penalties.

Required disclosures: Every TikTok competition must clearly state: who can enter, what the prize is, how the winner is selected, and when the competition ends. Include these in your video caption and link to full T&Cs from your bio. Add: "This promotion is not sponsored, endorsed, or administered by TikTok."

TikTok Competition Formats

TikTok's interactive features open up competition formats that don't exist on any other platform. Choose the format that matches your objective and audience.

Branded Hashtag Challenge

MOST VIRAL

Create a challenge and ask users to post their own video using your branded hashtag. This is TikTok's signature competition format. When it works, it goes genuinely viral — users create their own interpretation, their followers see it, and the chain reaction can generate thousands of entries. Judged on creativity, making it a game of skill (no permits needed). You'll need a solid set of Terms & Conditions covering your judging criteria.

Highest viral potential

Game of skill (no permits)

Massive UGC generation

Requires strong creative concept

Duet Challenge

GAME OF SKILL

Post a video and ask users to Duet it with their own creative response. Duets play side-by-side with your original video, keeping your brand visible in every entry. Works brilliantly for reaction videos, dance challenges, taste tests, and before/after reveals. Best results when the Duet is 10–20 seconds.

Your brand in every entry

Easy for users to participate

Users need to enable Duets

Less control over content quality

Stitch Challenge

GAME OF SKILL

Users clip up to 5 seconds from your video and add their own content after it. Your video becomes the intro, and entrants build on it. Perfect for "finish this sentence," "show us your version," or "respond to this question" prompts. The Stitch embeds your brand directly into the conversation.

Natural conversation starter

Your brand as the opening frame

Less visual than Duets

Users choose which 5 seconds to clip

Comment to Enter

SIMPLEST

The most straightforward option: post a video announcing the prize and ask users to comment to enter. Use a creative prompt rather than just "comment below" to make it a game of skill. Comments boost the video's engagement signals, helping it reach more people through the algorithm.

Lowest barrier to entry

Comments boost algorithm ranking

No UGC generated

No data collection

Landing Page / Link in Bio

BEST FOR LEADS

Direct users from your TikTok video to a landing page via your bio link. The video drives awareness and excitement; the landing page collects email addresses, phone numbers, and other data. Lower conversion than comment-to-enter but captures leads you can market to long after the competition ends.

Collects email & data

Automated winner selection

Extra step reduces entries

TikTok users resist leaving the app

Pro tip: Hashtag challenges and Duet/Stitch competitions are games of skill when judged on creativity. This means no permits required in any Australian state. This is a huge advantage over random-draw competitions, which may require permits in NSW, ACT, SA, and NT depending on prize value.

Creating TikTok Content That Works

TikTok's culture is fundamentally different from Facebook and Instagram. Polished corporate content underperforms. Authentic, raw, personality-driven content wins. Here's how to create competition videos that actually get traction.

What Works on TikTok

Authentic and unpolished: Film on your phone, not with a production crew
Personality-driven: Show real people, not just products
Hook in the first second: "We're giving away..." immediately grabs attention
Trending sounds: Use popular audio to ride the algorithm
Text overlays: Many users watch without sound
10–30 seconds: Short videos have higher completion rates
Clear CTA: Tell viewers exactly what to do

What Doesn't Work

Overproduced videos: Studio lighting and scripts feel corporate
Landscape format: TikTok is vertical (9:16) only
Long intros: Users scroll past within 1–2 seconds
Repurposed Instagram Reels: TikTok users can spot recycled content
No sound strategy: TikTok is an audio-first platform
Ignoring trends: Trend-jacking is core to TikTok culture
Walls of text: Keep captions concise; details in comments or bio

Competition Video Structure (10–20 seconds)

1

Hook

0–2 sec

"We're giving away a $500 [prize]!"

2

Show the Prize

2–6 sec

Unbox it, hold it up, show it in action

3

How to Enter

6–12 sec

"Follow us and comment your answer"

4

Urgency

12–15 sec

"Closes Friday — enter now!"

Step-by-Step: Running a TikTok Competition

1

Define Your Objective & Format

Brand awareness? Use a hashtag challenge. UGC content? Use a Duet or Stitch challenge. Leads? Direct to a landing page. Engagement? Use comment-to-enter. Match your format to your goal. See our complete business guide for detailed objective planning.

2

Check Legal Requirements

Hashtag challenges, Duet, and Stitch competitions judged on creativity are games of skill — no permits needed. Random comment draws may require permits based on prize value. Set eligibility to 18+ Australian residents. See our permits guide.

3

Write Terms & Conditions

Draft T&Cs covering all required elements, including content rights for UGC entries. Host them on a public URL and link from your bio. Include the TikTok disclaimer and specify eligibility as 18+ Australian residents.

4

Create Your Competition Video

Film a short (10–20 second) vertical video. Hook in the first second, show the prize, explain how to enter, and add urgency. Use text overlays for silent viewers. Use a trending sound if it fits. Keep it authentic — this is TikTok, not a TV commercial. Enable Duets and Stitches on the video if using those formats.

5

Write Your Caption & Select Hashtags

Caption: prize details, entry steps, close date, T&C link mention, and TikTok disclaimer. Use 3–5 hashtags: your branded competition hashtag, 1–2 niche hashtags, and 1–2 competition hashtags. Don't overload — TikTok prioritises keywords over hashtags in 2026.

6

Publish & Use Commercial Disclosure

Post the video and toggle TikTok's commercial content disclosure. Pin it to the top of your profile. Update your bio link to point to the T&Cs or landing page. Post at peak Australian times (7–9am, 12–1pm, 7–10pm AEST) for maximum initial engagement.

7

Promote & Engage Throughout

Reply to comments (video replies work especially well on TikTok). Post follow-up videos highlighting great entries. Create "last chance" reminder videos. If budget allows, boost with TikTok Promote or run a TikTok Ads campaign. Cross-promote on Instagram and Facebook.

8

Select & Announce the Winner

For skill-based competitions, have your judges review entries by hashtag. For comment draws, use our free Pick a Winner tool to randomly select a winner with an animated draw you can record and share. Announce the winner with a dedicated video — consider doing a live unboxing or delivery video for extra engagement. Tag the winner and notify them via DM. Publish their name as required.

Creator Collaborations

TikTok creators are the platform's lifeblood. Partnering with the right creators can seed your competition challenge and kickstart the viral loop. On TikTok, creator selection is about content fit and audience engagement, not follower count.

Nano Creators

1K–10K followers

Highest engagement rates
Most affordable ($50–$300)
Often product-for-post
Authentic, niche audiences

Micro Creators

10K–100K followers

Strong engagement + reach
Moderate cost ($300–$2K)
Established content style
Best ROI for most brands

Macro Creators

100K+ followers

Massive reach potential
Higher cost ($2K–$20K+)
Brand credibility boost
Can kickstart viral trends

Best strategy for competitions: Partner with 3–5 micro creators (10K–100K) in your niche to seed the challenge. Each creator posts their own take on the challenge, exposing your competition to 5 different audiences. This multi-seeding approach is more effective than a single large creator and often more affordable.

Disclosure required: All creator partnerships must use TikTok's commercial content disclosure tools and comply with Australian AANA advertising guidelines. Creators must clearly label content as #ad or #sponsored. Non-disclosure is a breach of Australian Consumer Law (misleading conduct).

TikTok Ads & Promote

While TikTok's organic reach is exceptional, paid promotion can accelerate your competition's visibility. TikTok offers two options: the simple Promote tool (boost an existing video) and TikTok Ads Manager (full campaign control).

TikTok Promote (Simple)

Boost your competition video directly from the app. Choose your goal (views, website visits, or followers), set your budget, and select your audience. Available from $5/day.

Set up in under 2 minutes
Target by age, gender, interests
Budget from $5–$500/day
Best for: Small budgets, quick boost

TikTok Ads Manager (Advanced)

Full campaign management with detailed targeting, A/B testing, retargeting, and conversion tracking. Create In-Feed Ads, TopView placements, or Branded Hashtag Challenge ads.

Lookalike audiences from customer data
Retarget website visitors
Branded Hashtag Challenge ads
Best for: $1K+ budgets, lead generation

Australian targeting tip: TikTok's Australian audience skews younger, so adjust your targeting accordingly. The strongest segments are 18–24 and 25–34. Use interest targeting aligned with your prize (e.g. "beauty" for a skincare prize, "gaming" for a console giveaway). Location targeting supports Australia-wide and state-level.

Common TikTok Competition Mistakes

Repurposing Instagram Reels directly

TikTok users can immediately spot recycled content from other platforms. Videos with Instagram watermarks or polished production styles underperform dramatically. Create native TikTok content that matches the platform's authentic, raw aesthetic.

Forgetting commercial content disclosure

Since 2026, all promotional content on TikTok must be labelled using TikTok's built-in disclosure tools. Skipping this can result in video removal, reduced distribution, and account penalties. Enable it before posting every competition video.

Making the video too long

TikTok's algorithm rewards completion rate. A 60-second competition video that most people abandon at 15 seconds will be shown to fewer people than a 15-second video watched in full. Keep your competition announcement under 20 seconds. Save detailed rules for the caption and T&Cs link.

No follow-up content

A single video won't sustain a competition campaign on TikTok. The algorithm moves fast. Post follow-ups: highlight great entries, create video replies to comments, show behind-the-scenes, and build urgency as the close date approaches. Aim for 3–5 videos throughout the campaign.

Ignoring Duet/Stitch settings

If your competition is a Duet or Stitch challenge, you must enable these features on your video settings before posting. By default they may be disabled on business accounts. Double-check before publishing or your entrants won't be able to participate.

Not specifying eligibility

TikTok is global. If your competition is open to Australian residents only, you must clearly state this in both the video and caption. With Australia's under-16 social media ban, specify 18+ eligibility to keep things clean legally. Include location and age requirements in your T&Cs.

Amplify Your Reach Beyond TikTok

Instagram Reels

Create a native Reel (not a repost) announcing the competition. Direct viewers to your TikTok or run the competition on both platforms simultaneously. See our Instagram guide.

Facebook

Share your competition on Facebook to reach an older demographic who may not be on TikTok. See our Facebook guide.

Competition Sites

List your competition on Competitions.com.au to reach thousands of compers across all demographics.

Email Newsletter

Include a thumbnail and link to your TikTok competition in your email newsletter. Embed the video if your email platform supports it.

Your Website

Embed your TikTok video on your website. Add a competition banner with a link to your TikTok profile or landing page.

In-Store

Display TikTok-style signage with your handle and branded hashtag. Include a QR code linking to your profile or competition video.
