If you mean The Sea and Summer, Bruce Gillespie tells me that Gollancz is going to reissue it, I don't know when – I will ask.

The short story collection is available from Bruce Gillespie, who made this comment on my facebook post alerting people to this blog post, he said: because most people in today's Australian SF scene have no sense of Australia's SF scene before 1990, I suspect most will not have heard of this major collection. Before he died, Peter MacNamara gave me all the stock of 'Pursuit' to continue selling, so I can still provide copies: $25 to 5 Howard Street, Greensborough VIC 3088. Mark cheques 'Bruce Gillespie'.

I'd be interested in the novel. Do you know where's its available?
