That does raise a few issues.
She was attracted to his political style from afar. I would think the particularly dirty muck raking style. He seems to have the back streets of Glasgow written all over him.
On his being single I can't confirm although he does spend an awful lot of time with the PM. If he is married that could make him very attractive to Gillard she has had her fair share of affairs with married men.
I have seen little of Tim lately and can't confirm he went to PNG, although he does prefer a more up market destination.
I think the reality that Gillard would have to split her pension with Tim if they separate has kept them together. That in itself makes dating for the singles out there so much safer.
After 14 September he will be on his way maybe off to create political conflict in other place, maybe Syria.
