I believe APNIC requires you to be a registered company unlike RIPE who will allow individuals as customers, but the flip side is that becoming a company in Australia is quite easy paperwork, unlike in Germany where you have to put up a $25000 bond.
Edit: APNIC also wants you to provide some plans for your network upfront while RIPE NCC is more willing to just assume good faith. But their requirements do not seem onerous, and you are not held to the plans, it's just to check you have a need for the resources.
In germany you can register an UG for around 40€, thats way cheaper than a regular GmbH
APNIC also has the advantage of having /24s reserved for new applicants (last I checked)
Registering a company in Australia is virtually free. APNIC fees, on the other hand, are much higher than what you'd pay with RIPE. It's pretty hard to justify a minimum of $1300 a year + a $500 sign-up fee just to have a personal ASN that you don't need unless you want to run a full table.
