25OFF
Any purchases on Adrenalin.com.au will qualify for the $25 discount.
The website doesn't say how long the promotion will last.
You also need to factor in a $3.50 administration fee for all purchases.
I didn't need to type the code on my booking. The promo code was automatically filled in with 25OFF.
The discount worked on my booking for the Ultimate Supercar Track Day - Marulan:

The 25OFF will work on $100 gift vouchers too. You can read about how to pay with multiple vouchers off another Adrenaline post here:

There's also a separate movie ticket promotion. If you purchase an Adrenalin Gift Voucher ($100 minimum) AND have them delivered via snail mail, there's an option to select double movie pass for "Ender's Game". The Adrenaline website doesn't mention which cinemas.

This is my first purchase on Adrenaline. I paid my booking using credit card for added protection. I read on my Adrenaline confirmation screen that the amount isn't debited until the booking gets off the ground. The drive experience I booked is already 75% off normal RRP which is plenty in savings.
UPDATE: Looks like my booking for Monday is going ahead. So far so good.
I once bought a gift voucher from adrenalin.com.au and a few months later when I went to use it the company went into administration. Then adrenalin.com.au reappears in a very similar format to the original except they dont honour my gift voucher. Never again will I buy a travel voucher from a website unless I was going to use it the next day.
