For the select few with the right citizenship. Everybody else queues up to talk to immigration. During busy time it can take 2h. The self serve kiosks are not the norm.
Travelling to Australia as a New Zealand citizen is about as easy as it gets. My last flight from Sydney to Auckland I was at home 45 minutes after the plane landed.
This has become a lot better in the US now too - I can use my Australian passport at their self-serve kiosks when travelling on an ESTA that has a renewal.
You still have to talk to the immigration officer though - everyone does.
