The 1st 410 which you do in 2005 will qualify you for silver until end of 2006. The next 300 will renew you for silver through to end 2007.
The points will not converge to give you gold. Alternatively, you could open a new QF ff account which starts in December 2005. You would then reach Gold status which would last till end of December 2007. You would then drop to silver until end of Decmber 2008 if you failed to requalify for gold. Your Qantas Club membership will be suspended as soon as you attain gold and will be reactivated once your membership status drops back to silver
"Also, what would be the least amount of money you could spend to get to Gold. Thought it might be interesting. I calculated around $7200, but thats a heck of alot of domestic trips and many hours at the QP!!."
I have done it for under $5000 with a 1st class return from FRA to MEL
