Last Friday's activities included preparatory activities such as bridge reinforcement works. An Adani spokeswoman said inductions were also being carried out onsite and that would continue as the workforce increased.
"With approvals now in place, our focus is on ensuring the establishment of a safe and environmentally compliant worksite as we get on with the job of delivering the Carmichael mine and rail project," she said.
"In order to let our team safely get on with their work, we do not intend to be providing a running daily commentary of work activities."
The Australian Conservation Foundation said Adani still needed further approvals and management plans before it could start digging and shipping coal and that the Wangan & Jagalingou Family Council still had a legal challenge in the courts.
"Adani also doesn't have a contractor to build the mine; doesn't have an insurer; and has no access to Aurizon's rail line or leases for rail construction," it said.
An Adani Mining spokeswoman said details on insurance providers for the Carmichael project were commercial in confidence.
"However, we have the requisite insurance requirements in place," she said.
The spokeswoman also said that details of Adani's rail arrangements were commercial in confidence.
