G'day Barry,

I see Alan has not yet got back to you, so I will give a quick glossary:

The Old Man Plain is a (generalised term, not official name) wide desert area (back of beyond, as it were)

The Darling Pea is an illness from eating a native plant (usually suffered by your horses or cattle ... but after a bender ... who knows?

Hard yakka = hard work, hard grafting

The Lachlan is a river and a valley down in the cooler south of New South Wales.

Regards,

Bob Bolton
