University fees are ridiculously high for international students so I don't think you can count on studying in Australia unless you've got tens of thousands of dollars saved up; those on student visas are also forbidden from working over a certain number of hours a week so earning a living would be very difficult too.
My family are pretty well of ish, but typical like most desi families very tight with cash, as if they're going to take the money to their grave or something. So the money problem I am not too worried about, actually I was one of the members on here who wanted to see higher tuition and university fees in the UK. That didn't go down too well. lol.
Highly doubt my father will ever give me money for tourist holiday.
Btw, if you're 30 why would you need your parents' permission to travel? And why the need to lie to your wife and parents?

I don't need their permission if it was my own money, but since it's their money I need their permission. If you get what I mean, I don't work I'm a freeloader, I find it easy and very enjoyably to spend other peoples money. Lying to the wife, is something which I need to do, otherwise she would not agree with the idea, she's already trying to push me into getting a job so I can pay my dad back for the house he bought us. She's out of her mind.
I have a entailment mentality, I was spoiled as a kid trying to change that now is too late. I've hardly ever worked for anything.
