I'm based Australia and have used Cloudflare for personal/business; if you aren't on the $200/month plan for your website then you don't get (consistent) access to the Australian-based servers for your visitors (they may be routed to eg Singapore instead during some times of the day) which actually hurts performance if your service is located in (say) AWS/Azure Australia region, at least for the CDN aspect, I assume the same for Workers too.

Same here in New Zealand too. Cloudflare peers only with certain ISPs. The ones they don't peer with sees some traffic (e.g. sites on free plans) routed to offshore Cloudflare POPs around the world instead of local Cloudflare POPs. I understand if the website is on a paid plan they will be more likely to route to a local POP (incurring more costs in doing so).

According to this 2016 post, the problem is Optus and Telstra, and the costs of peering with them (scroll down to "Oceania"):
