I feel I should know this one! This is the first time I have seen this woody weed in the Woodland.

Some Prunus species have spines like this but I couldn't say which one this is. I will try to find my photos of one in Mugga, which had blossoms.

Some Prunus rootstocks may have spines and if they sucker they can grow as a plant. Citrus rootstock may also be thorny.

Prunus spinosa (blackthorn) has spines on branches is an environmental weed in some parts of Australia..

Ruth, at first I thought it may be one of the hawthorn species planted in Woden and which we have had as weeds on Red Hill, (Cockspur Hawthorn - Crataegus crus-galli or Washington Thorn Crataegus phaenopyrum) but the leaves are wrong. I'm pretty sure it is a Plum, possibly Prunus Americana.

I think it is a plum too - Prunus Americana is/has been used as rootstock.
