The chart you link to shows that Brown Coal, as both a total, and as an overall percentage of the grid, is decreasing, with renewables increasing.

Indeed, if you look at the three Brown Coal generators in Victoria[1], Yallorn is due to shut down in 2028 taking ~30% (1480MW) of that away, followed by Loy Yang A in 2035 which will take another ~40% (2200MW) of that capacity.

So, banning new LNG appliances now, and starting that migration will have a net positive impact.

This is true even if the LNG continues to be burned overseas if it's replacing coal fired generation capacity.
