for this type of tasting just bend the 3 white, 5 red thing (tell em sweet wines are reds

)
yeah perhaps my list but replace champagne with a good typical eden valley or claire valley riesling?
Perhaps
Wither Hills Sauvignon Blanc
Grosset Watervale Riesling
Kumeu River Chardonnay (or a typical mid priced Margaret River example - someone else can advise)
Carrick Pinot Noir (or Felton Rd)
Saltrams Mamre Brook Shiraz (or Grant Burge Filsell)
Wynns Coonawarra Cab (or majella)
Noble One (this can cover off semillon)
And someone else will recommend a fortified
Shouldnt break the bank. Not quite up with your prices over there but you could in fact upgrade the shiraz or cab a bit
You could swap out a white for
Merlot - Perhaps Esk Valley Reserve or Mills Reef Elspeth
I reckon including obscure varieties just to get a 5-3 split will detract from the whole "typicity" aim and will be a waste of space for your type of audience.
