as long as the balance you can still advance exceeds the minimum allowable amount (around 160-161) then yes, you can get it any time

as consultants, we are concerned about people taking out massive advances and putting themselves under financial strain to pay them back - one decent advance can leave them paying back 77 a fortnight! so we're trying to encourage people to do exactly what you've done Anila
Yes, its more than the minimum that i have remaining, saving that for an emergency use now that i know i can apply any time for it!

Thanks hun.
