Processing works in a way that they send invitations to candidates with most points lets say 75, then if quota isn't met to those with 70 then 65 and then to 60. If some of 60s didn't fit into this month they will be first on the list for next month (after all the 75, 70s ans 65s).
They also had raised amount of points to apply in the past...
However I suggest you don't even try... Australian system is rigged in such a way that they can report that you have some amount points (say 60), but then after you have paid application fee 2k USD, they can change them (to 55) and you cannot complain about it because they get to decide everything... You can't even appeal it or complain to anyone... they can just take your money and there is nothing you can do about it...
