Former Qantas workers are claiming victory over its $90 million fine for illegally sacking more than 1800 workers.

The court's found outsourcing baggage handlers, cleaners, and ground staff in 2020 was done to curb union bargaining powers.

Qantas says this judgment holds them accountable.

Australian Correspondent Lesley Yeomans told Ryan Bridge $50 million of the fine will be going to the Transport Workers Union, and what happens with the other $40 million will be decided at a later date.

Another dairy sector shake-up.

Infant formula and dairy company a2 Milk is buying the Yashili plant in Pokeno and selling its majority stake in the Mataura Valley plant in Gore to Open Country Dairy.

A2 Milk's announcement comes as it reports a 21% rise in profit, off the back of a 9.3% rise in revenue.

Forsyth Barr Senior Analyst Matt Montgomerie told Ryan Bridge a2 has stood out over the last couple of years, consistently exceeding expectations despite operating in a relatively tough formula market in China.

He says the decision to acquire the plant in Pokeno is quite a big step in continuing that growth pathway.

Praise for new building consenting rules.

The Government will change liabilities, holding parties responsible for their share of work.

Certified Builders Chief Executive Malcolm Fleming says the building guarantee or building system should be mandated.

He told Ryan Bridge that will add cost to the price of building, but it's minuscule in the scale of things.

Fleming says on a $500,000 project, a guarantee would cost just $1,500.
