Back home after 2 months touring Australia

Now that i am home and finished my travels for now, its time to shift this debt!!! I plan to make the minimum payments to all but one debt. The loan of £45,000 has the higest interest of over 12%!! my plan is to use my local credit union and borrow £5000 at 5% and put that towards the loan. Pay that off in 9 or 10 months and do it over again. Anyone else tried this method?
