SMH journalist Roy Masters has, for decades, "specialised" in writing articles on off-field NRL and AFL developments/strategies.
In the Annual Tom Brock Annual RL Lecture on 19.9.208, he said:-
. in the next 10-20 years, it is probable "...the AFL...moving into Campbelltown with a great deal of wealth and resources" ie he is predicting a side based in the Sydney's SW, or southern suburbs (at about 37 minutes 20 seconds).
."rural NSW is under siege" ie significant GR RL decline, & growth of GR AF (at about 39 minutes 30 seconds).

GR AF regd. nos. are booming in 2019 in Sydney, & throughout NSW/ACT. In 2019, GR regd. nos. will surpass WA.
The link below has figures for the NSW North Coast (ie north of Newcastle, not including the Newcastle/Hunter Black Diamond comps.). The North Coast was, until recent years, a very barren area for GR AF. In 2019, there will be a record 33 jnr. teams, in 10 Clubs- numbers have doubled since 2015. Snr. GR nos. are also having good growth.

Sorry BBT but I don't think Roy Masters was predicting an AFL team in Campbelltown anyway but he would also have no basis to make that prediction.
He said it in the context of the AFL's growth in the reverina. He was referring to grass roots development not starting and AFL club there
That was an interesting listen overall. It is amazing how much the AFL dominated discussion (though pretty much absent of negativity apart from Roy Masters)
