Sydney airport parking - maximum Velocity earn?

Hello

SYD international parking is operated by Wilson who offer Velocity points earn when you use their Book a Bay service. Unfortunately I can’t Book a Bay at the international airport, so wonder if anyone knows a way to earn maximum Velocity points on the booking, apart from using a credit card?

Cheers.

No experience in this but if you are super keen, ring up Wilson Parking and tell them your situation and perhaps they can make a booking from their end that could earn velocity points too.
