Both a verb and a noun.

Verb- to flirt. Putting in effort to try to win a girl over.

The noun is 'one who garries'. A guy who is very flirtatious with girls.
Also, 'garry' can be used for the abstract noun meaning 'flirtatious energy' (perhaps synonymous with 'mojo'), ie. "My garry has been a bit weak lately".

The term garry is thought to originate in an advertisement on Australian TV in the early 2000s, for a flavoured milk, apparently called Garry Milk. In the ad, the milk was so good, it would flirt with girls. Something like that. School students in Melbourne north-eastern suburbs adopted the use of 'garry' from this source.

The other theory is that the term 'Garry Groundwork' has been used in certain social circles around Melbourne for years, with the female counterpart 'Fiona Footwork', both meaning someone who is putting in effort to win someone's heart. It's possible that the milk ad was written with these terms in mind.
