Do i have enough time....

I wanna do scuba diving,go to Cairns(especially Great Barrier Reef) and surfing..with barely 3 months left,do i have enough time?Or must i make a choice between the 3,to go for only 2 of them or worst,just 1?!!

NO!!I don't wanna come to a day when i have to make such decisions!Oh man!I must really start planning my time now so that i can make it for all!No way am i gonna miss out on any when it's a once in a lifetime thing,well,since i'm in Australia,and i'm not sure when's the next time i'll be popping by again,i might as well make my stay here useful.....

So,wish me luck on organising my time,or shall i say squeezing these activities on top of my Uni deadlines.....
