UNIONS have given cautious support for the Federal Government after they formed a "working group" to deal with the dangers of asbestos in rolling out the National Broadband Network.
The toxic fibres were unearthed and, in some cases, left exposed during works in New South Wales, Victoria, South Australia and Western Australia.
In Queensland, the white spores dusted a busy street in Mackay's city centre for five days before being shoddily cleaned up.
The Electrical Trades Union and Communications Electrical Plumbing Union released a statement on Thursday which described meetings as positive but that it was too early to know if they would be a success.
Both unions said they were committed to ensure workers and contractors working on the NBN expansion had been properly trained.
