With a new job, the most important thing is to start with a new mug. I tried to find a nice one at CafePress, but there weren't really ones which would make me happy. So I made a couple myself :-)
The first batch has the BUGS (BSD Users Group Sydney) logo on it and are available from CafePress - BSD Users Group Sydney. Just mugs, that's all.
The first batch has the FreeBSD logo on it and are available from CafePress - FreeBSD Users Goodies. Mugs and stickers!
I have put a markup of one dollar per 10 dollars in price (and 50 cents for everything less than 10 dollars), which will be donated to the FreeBSD Foundation as described on FreeBSD Foundation Donations.
There are many more items available, for example clothing, but it's way too tricky to define them all in advance. If you want to have something, let me know and I'll add it!
