Nope, they're not Australian things. Basically dips are just like spreads, you put them on biscuits to give it more flavour. As for jelly, you've got the right picture of it.
I've never heard of the things you're talking about, burma and kurabia. To me, judging from the picture, burma looks like a proper meal rather than a dessert. It looks like a better version of rice paper rolls to me. I can't tell or not from looking whether I'd enjoy eating it.
The link to that second picture doesn't work.
I don't know whether a Yule log is just limited to France, but I don't know what it is myself.
Our relatives (aunts, uncles, cousins, etc) wanted to do their own thing on Christmas, so I just ended up spending it with my immediate family. It's not a big deal to me, really, just a little bit more special than a normal day, and I agree, having a break is good.
