The Trade and Investment Minister's in Australia to meet with his counterpart

Todd McClay's planning to sit down with Trade Minister, Senator Don Farrell, and the Australia New Zealand Leadership Forum.

It's expected issues with dairy matters will dominate discussion, and a letter written by the dairy industries within New Zealand, Australia and the US, most particularly.

Geopolitical analyst Geoffrey Miller says it's all about Canada dumping dairy protein onto the market.

He says the letter alleges Canada's selling it at very low prices - lower than the cost of production.
