From what I can gather from the ABC Web program, ABC1 will show Collectors at 2000 then George Gently at 2030, and from 2000 VFL Grand Final on ABC HD (native, if the promo Neon Kitten refers to is correct). There is some information about this on the ABC program page. Just hover over the program entry for George Gently in the main program. It's got different information in it from what you get if you click through. Then at 2200, the VFL will continue on both services. Apparently.
There's nothing in the ABC Web schedule to indicate that the VFL starts at 1900, but if that's what thery're advertisng, then I guess it starts then.
