is his monastery's address, and the phone number listed is +61 (0)8 9525 2420 but I'm not sure if he himself ever speaks over the phone. Best bet would be to call and ask where the best place to write is, or to just write to that address and see what happens!
Gain and loss, status and disgrace,
censure and praise, pleasure and pain:
these conditions among human beings are inconstant,
impermanent, subject to change.
Knowing this, the wise person, mindful,

Desirable things don’t charm the mind,
undesirable ones bring no resistance.
His welcoming and rebelling are scattered,
gone to their end,
do not exist.
