Short answer: it depends on platform and objective, but top Australian creators you should consider for ad campaigns (by short-form, long-form, gaming, lifestyle/beauty and food niches) include:

Short-form / TikTok & Instagram creators

• Anna Paul — lifestyle/beauty creator with multi‑platform reach and a big TikTok/IG audience (great for fashion/consumer brands). (sproutsocial.com)
• Bridey Drake — highly engaged, relatable TikTok creator (strong for authenticity-driven brand ads). (news.com.au)
• Xavier Di Petta (PartyShirt) — viral TikTok creator with massive follower counts and strong short‑form storytelling. (en.wikipedia.org)

YouTube / long‑form & creator-led campaigns

• Wengie — Chinese‑Australian YouTuber who’s run international product/brand collaborations and music tie‑ins; good for global reach & product launches. (en.wikipedia.org)
• LazarBeam (Lannan Eacott) — one of Australia’s biggest YouTubers (gaming/comedy); ideal for youth, gaming, and large‑reach awareness campaigns. (en.wikipedia.org)
• Lachlan (Lachlan Power) — major Aussie YouTuber/gaming creator and founder of the PWR network — useful when you want creator networks + scale. (en.wikipedia.org)

Gaming creators (highly effective for Gen Z / male-skewed audiences)

• Muselk (Elliott Watkins) — established Aussie gaming YouTuber. (youtube.fandom.com)
• Loserfruit (Kathleen Belsten) — top Australian streamer who’s worked with brands (and even has a Fortnite Icon tie‑in). Great for cross‑platform gaming activations. (en.wikipedia.org)

Niche / category specialists (better for targeted product fits)

• Shani Grimmond — beauty & lifestyle (strong for cosmetics, swimwear and DTC fashion). (influencenewsnow.com)
• Michael Finch — food creator/chef — good for food, FMCG, kitchen appliances and recipe-driven ads. (influencenewsnow.com)
• Sarah Magusara — family/fitness/mom creator (strong for health, wellness, family brands). (hobo.video)

Creators + production/filmmaking talent (for high‑production commercials)

• Established Australian commercial directors and production houses (e.g., Husein Alicajic, Tim Piper, The Monkeys) — good if you want cinematic or award‑level TV campaigns rather than influencer content. (en.wikipedia.org)

Quick guidance for choosing:

• Platform match: use TikTok/IG creators for short, performance-focused social ads; YouTubers for longer storytelling/brand films.
• KPI fit: choose creators by engagement and audience fit (not just follower count).
• Creative control & assets: higher production + creator involvement costs more but yields better creative and ad assets you can reuse.
• Compliance & measurement: negotiate usage rights, conversion tracking, and deliverables up front.

If you want, I can:

• Narrow this to a top 5 tailored to your platform, budget and audience; or
• Pull follower/engagement stats and recent brand works for a shortlist you can pitch to (I can fetch live metrics).
