There is no single best time to post on Instagram in Australia. Anyone who gives you one exact hour is guessing about your customers. The best time is when the people who buy from you are on their phones, and Instagram will tell you when that is, for free.
Here is how to find your own best times, a few sensible starting points while you work it out, and the one Australian catch most guides from overseas miss: our time zones.
Why one "best time" does not work
A cafe in Newcastle, a plumber in Ballarat and an online clothing shop selling to all of Australia have very different customers. The cafe's people scroll before work and at lunch. The plumber's customers look at their phones after dinner, when they finally notice the dripping tap. The clothing shop's buyers might be on at 9pm on a Sunday.
So the question is not "when is everyone on Instagram?". It is "when are my customers on Instagram?".
Step 1: Look at when your followers are online
If your Instagram account is set up as a business or creator account (a professional account, it's free), Instagram shows you when your followers are most active. Here's where to find it:
Open your profile and tap Professional dashboard.
Tap Account insights, then Total followers.
Scroll down to Most active times. You can switch between hours and days.
Instagram shows these times in your phone's time zone. If your followers are mostly local, that's your answer for where to start. Instagram only shows this once your account has enough followers, so if the section is missing, use the starting points below for now.
Step 2: Use these starting points while you test
These are not magic numbers. They are the moments in an ordinary Australian day when people tend to pick up their phones, and a good place to begin:
Early morning, around 7am to 9am: breakfast, the commute, the coffee queue.
Lunch, around 12pm to 1pm: a quick scroll between jobs or at the desk.
Evening, around 7pm to 9pm: the kids are fed, the couch is free. This is often the strongest window for anything people need to think about, like a quote, a booking or a gift.
Match the time to the business. A bakery's fresh batch belongs in the morning. A tradie's "jobs we finished this week" post does well in the evening. A shop's weekend specials can go out on Friday night or Saturday morning.
Step 3: Mind the Australian time zone trap
This is the part overseas advice skips. Australia has three time zones in winter and five in summer, because not every state uses daylight saving.
From the first Sunday in October to the first Sunday in April, New South Wales, Victoria, the ACT and Tasmania move their clocks forward an hour.
Queensland does not. So in summer, 7pm in Brisbane is 8pm in Sydney and Melbourne.
South Australia moves forward too, so Adelaide stays half an hour behind Sydney all year.
Western Australia and the Northern Territory do not change. In summer, Perth is three hours behind Sydney.
If your customers are all in your own town, none of this matters. If you sell across the country, it does. A post that goes out at 7pm Sydney time lands at 4pm in Perth, when people are still at work. If a lot of your followers are in the west, try a second time in the evening there, or pick a time that suits most of them.
It also matters when the clocks change. A post you set for 7pm Brisbane time in October will reach your Sydney followers an hour later than it did in September. Check your posting times in early October and early April.
Step 4: Test for a month, then keep what works
Pick two or three times that make sense for your business and post at each for a few weeks. Then look at what happened. On each post, tap View insights and see how many accounts it reached and how many people saved, shared or commented on it.
Compare like with like. A photo of your best product will beat a photo of the car park at any hour, so try similar posts at different times. After a month you'll have a clear favourite or two, and that's your schedule.
What matters more than the time
Timing helps a good post get seen. It cannot save a post nobody wants to look at. Three things matter more:
Posting regularly. Two good posts a week, every week, beats a burst of ten and then a month of silence.
Sounding like yourself. A caption that reads like a real local business gets read. One that reads like a brochure gets scrolled past.
A clear, real photo. Your own work, your own shop, your own people. It doesn't need to be fancy.
Making it easy to stick to
The hard part is not knowing the best time. It is having a post ready to go at that time, week after week, when you're flat out.
That's the job ContentPilot was built for. It drafts your posts in your own voice, you approve each one from your email with one tap, and it goes out on Instagram, Facebook and your Google Business Profile at the times you chose. Nothing goes out without your yes. You can start free with 50 credits, no card needed.
