Best time to post on TikTok in Australia.

The short answer: for Australian accounts, the strongest TikTok windows are weeknight evenings from about 6pm to 11pm and weekday mornings from 8am to 11am, east coast time. Tuesday and Thursday are the best days. Sunday is the weakest. That's what the only large Australia-specific study says. Now the bit that matters more: on TikTok, when you post decides the first hour. What you post decides the next three weeks.

What the Australian data actually says

Sprout Social published the only big study I can find that's built on Australian accounts: over 68 million Australian engagements across six platforms, with times listed in AEST. For TikTok it found:

• Best days: Tuesday and Thursday.
• Worst day: Sunday.
• Best windows: scattered, but they cluster in the morning from 8am to 11am and late in the evening, right up to 11pm.
• Tuesday has the most good windows of any day, six of them, running from 6am to 11pm.

That evening lean makes sense. Australians spend about an hour and 14 minutes a day on TikTok, more than any other social app here (DataReportal, August 2025). Most of that isn't the lunch break. It's the couch after dinner.

Why the big global studies contradict each other

Here's what the other guides skip. The two biggest global studies don't agree on much at all. Buffer looked at more than 7.1 million posts and found Sunday at 9am was the single best slot and Saturday the best day, with afternoons the weakest part of the day. Sprout's global study, built on nearly 2 billion engagements, found close to the opposite: Tuesday to Friday from 2pm to 6pm, with weekends the worst.

Same platform, same year, opposite answers. Nobody's lying. It just shows the "best time" depends on whose accounts are in the data, where they live and what they post, and neither of those global studies is Australian. If a guide gives you a best time without saying whose audience it's built on, treat it as a guess.

Watch the time zones too. Sprout lists its Australian times in AEST, but from October to April, Melbourne, Sydney, Canberra and Hobart are on daylight saving, Brisbane isn't, and Perth is up to three hours behind the east coast. Post for your audience's clock. For most venues and local businesses that's one city, which keeps it simple.

Why timing matters less on TikTok than anywhere else

TikTok doesn't just show your video to your followers and call it a day. It tests the video on a small group of people, watches how they respond, and keeps pushing it out in waves if they watch to the end, rewatch, share and comment. TikTok has said follower count isn't a direct factor in what it recommends. That's why a video can sit quietly for days and then take off.

What timing does decide is who sees it in that first test. Post at 3am and the people around to judge it are few and half asleep. Post at 8pm on a Tuesday and there are plenty of people scrolling to give it a fair go. That's the real value of a good time: a fair first test. It won't rescue a weak video, and a strong one finds its audience anyway.

So the order hasn't changed: what you post beats how often you post, which beats when you post. If your TikTok views are flat, it's almost always one of the same three content problems that stall Instagram, and no amount of 8pm posting fixes them.

The hospitality version: post before the decision

If you run a venue, the question isn't when TikTok is busiest. It's when your customer is deciding where to go. And since the under-16 ban took effect on 10 December 2025, the Australian TikTok audience has shifted older. That's good news for venues: more of the people scrolling can actually book a table or buy a drink.

• Lunch trade: post from 8am to 10am, while people are planning their day.
• Dinner trade: post from 3pm to 6pm, before anyone's committed to cooking, then let the evening scroll carry it.
• Weekend bookings: post Wednesday or Thursday evening. That's when the group chat makes plans, and Thursday is one of TikTok's best days here anyway.
• Events and functions: post at least two days out, while plans are still soft. Same rule I use for filling Christmas functions.

A dinner video posted at 7:30pm on a Saturday is advertising to people who've already eaten. And if you're still deciding whether your venue needs TikTok at all, I've answered that honestly here.

How to find your own best time on TikTok

Your own numbers beat any study, including this one. In the app, open TikTok Studio, go to Analytics, then the Followers tab, and look at when your followers are most active. Check which time zone it's showing before you plan around it. Then do the simple thing almost nobody does:

• Post three videos a week for a month, in the windows above, on the same days each week.
• After the month, write down when your top five and bottom five videos went up. If there's no pattern, and there usually isn't, timing isn't your problem.
• Pick times you can stick to. Posting at 8pm every Tuesday beats posting at the perfect minute for three weeks and then giving up.

Cross-posting the same videos to Instagram? The windows are similar but not identical. I've covered the best time to post on Instagram in Australia separately, and the best day of the week too.
