Disembarkation in Perth/Fremantle -- Customs/Immigration???

Our cruise begins in Auckland, NZ, and ends in Perth, AUS. What type of customs/immigration will be required for us to disembark.

The ship arrives at 06:30am on a Monday morning, and the earliest flight Choice Air will book a flight is at 12:30pm or later. Does this seem right?

Can I expect to be able to disembark at 08:00am and catch private transport to the airport for an 11:30am flight?

I've only disembarked at Freo once, so hopefully others with more experience will chime in.

However my guesses:

Assuming arrival is on sched at 06:30;

Express walk off at 07:15;

Customs / Imm thru by 07:40; (this assumes nothing to declare which agriculture requires to inspect; eg wood, plants, food etc);

In taxi at 07:50;

Arrive at airport 08:40.

Therefore you should be OK for an international flight at 11:30 as long as the ship is cleared by around 07:00 - 07:30

Is it one or two hours check in time for a domestic flight?

If departing from one of the domestic terminals 1 hr is OK.
