From my Halls Gap 1:25000 map I read the summit of Bellfield peak as 6347 (e) 58856 (n) , which is shown in the Baxter guide as GR 347856.
Punched into the Redfearns calculator spreadsheet that I downloaded from ga.gov.au (zone 54, east 634700.00, north 5885600.00) gave 37 09 58 E 142 30 57 N which is fairly close to a GR that I've got for the top of Rolling Thunder which is a bit south of the summit.
