As an alternative to simulating latency: How about using a VPN service to test your website via Australia? I suppose that when it easier to do, it is more likely that people will actually do this test.

That’s going to give you double (plus a bit) latency as your users in Australia will experience.

Rent a VPS or physical server in Australia. Then you will have approx the same latency accessing that dev server, that the Australians have reaching servers in your country.
