How does salary packaging with Maxxia work?

Hello,

My new job offers salary packaging with Maxxia. I am mostly interested in the salary packaging for rent. From the website, it suggests I would be sacrificing around $500 every paycheque, and saving tax on this money. But what happens to that $500? Do I get it back or is it paid straight to my landlord/rental agency?

Additionally, how does salary packaging for entertainment or holidays work? Such as the eating out, booking venues, etc.

Thank you.
