For a late addition i would use EKG, for bittering there would be lots of choices, EKG, Target, Northern Brewer (both higher alpha descendants of Golding) Nugget, Bullion... (clue to ancestery in the names). Really any hop would do for low to moderate bitterness, say 10-40 IBU.
Fuggle or Stryian (a Fuggle not a Golding descendant) would be OK for bittering but in recipe calling for any of the 20 or so versions of Golding, EKG is regarded as the best UK finishing hop.
If you are interested there are lots of good articles on the history of hops in the UK.
WGV was popular in a time when seeded hops were trendy (around when Wheeler was writing), unfortunately not available in Australia they are a prohibited import, odds on you won’t see them here, even if it is still being grown.
First choice for me would be Target for bittering and EKG late.
