Queensland laws I'm especially fond of;
Must of held Automobile P's for 12 month period before Bike License is allowed
Restricted to 250CC for the period of probationary and permit motorcycle license (3 years-ish)
No passengers, AT ALL under 8 years old.
No passengers before 12 months of license.
There's 1 or two more that're just as good, But I don't recall them.
