The thing that is very obvious about Casuarina glauca is the extremelt long branchlets (to 38 cm long). Cones can be used for identification, but are a minefield, even in the hand. The number of teeth between segments of the branchlets can help with ID. However, in this photo, it looks as if the branchlets are too old to still have teeth.
A local moderator might know the site and what is there.

Nope, not going there. In general C. glauca is very abundant at Bawley Point, but this thing looks like it is in a yard, so could be planted. Allocas littoralis looks possible, even likelier, from the fruit size.

Branchlets too thick for A. littoralis.
The who,e of the Bawley Point essexite soils is covered in C. glauca, well inland. Due probably because of poor drainage qualities of this type of soil.

This is one of many Cas. Left remaining in local yards I would think since before subdivision of old farming property. This one has been heavily pruned in the past. Typically in this immediate vicinity are only C. glauca. Bark here is also consistent with glauca., definitely not littoralis. What seems odd with this one .... both male and female characteristics, viz: bearing fruit as well as male flowers at end of branchlets. Fruit seem a bit longer than other local glaucas, but not as large fruit as most littoralis.

Yep, having flowers of both sexes is unusual, and I did think the fruits looked overly large for glauca. However, your arguments have convinced me so I've confirmed it.
