I'll answer my own question, since nobody else did. Extensive search of printed and on-line information gave no answer. Ilford Australia's email address bounces. I looked at times in different developers for Tri-X, and came up with 9 minutes at 1+29 dilution. Since my tap water comes out at 24C at the moment, I fudged this to 6.5minutes, using Ilford's temperature correction chart. I'm happy with the result---I got good looking negs.(posted 9124 days ago)
