Up to another 50 were to be deployed on Friday, as well as an additional 40 ADF personnel, which would bring the contingent up to 116 so far.
Major General Jake Ellwood described the situation as "volatile".
"We don't provide details about our rules of engagement, but what I can tell you is that our soldiers, sailors and aviators can protect and defend themselves," he said.
Soldiers and police from Australia are also afforded immunity: They "shall be immune from arrest, detention and all legal proceedings in Solomon Islands courts and tribunals in relation to actions that are taken in the course of, or are incidental to, official duties."
The treaty adds that they "shall not be compelled to appear or give evidence in legal proceedings of any kind in Solomon Islands courts and tribunals", however, Australia can waive that immunity.
Additionally, Australia — with the consent of Solomon Islands — may invite third states to contribute to the deployment.

"We sincerely regret and strongly condemn the [Solomon Islands] government's decision to establish diplomatic relations with China," Taiwan's President Tsai Ing-wen said at the time.
Malaita Province Premier Daniel Suidani has been outspoken in his opposition of the national government's decision to switch to China, and South Pacific geopolitical researcher Ed Cavanough said there was evidence that a relationship between the province and Taiwan remained in some form.
Taiwan provided COVID-19 assistance such as personal protective equipment and food aid to Malaita, which Mr Cavanough said was in contravention of national law in Solomon Islands.
"I have been in contact with the governments of Australia and Papua New Guinea, seeking their assistance to assist our country, which is forthcoming," he added.
The Prime Minister requested Australia's help under a security treaty the country signed with Australia in 2017.
The former high commissioner to Solomon Islands, James Batley, said given the Solomon Islands had initiated the request under the treaty, Australia was obliged to intervene.
