From Foxtel’s Customer Updates on their home page:
On Monday 17 September 2018, FOX SPORTS 501 will be rebranded to FOX CRICKET, a dedicated 24/7 cricket channel. FOX CRICKET will have every ball & every wicket of every Test Match, ODI, T20, BBL Match and Women’s International Match in Australia, ad-break free during play. Some of the FOX SPORTS 501 content and regular programming will be moved to the other FoxSports channels included in the Sports Pack.
I guess this means the new channel will be set to go for their first broadcast of the new deal, which is a JLT One-Day Cup match between WA and NSW from the WACA on 18 September!
