Replacement flooring advice

Gday,
I recently bought a house which has carpet and i would like to have timber floors. The majority of the house has hardwood T&G boards. The problem i have is that part of the floor was damaged in a house fire some years ago and the builders just cut out the damaged boards and replaced with the particleboard flooring. The particleboard probably takes up 8 sq. metres. I intend to just replace the particleboard by staggering the new boards and cutting out a section of the existing old boards.
Do i need to get recycled floors as to eliminate the problem with moisture and expansion of the boards? Or can i get away with putting in new boards that may not have been kiln dried?
If i do need to get recycled boards are there any suppliers in brisbane that you would recommend?
The house was built in the 70's and its two storeys. I am putting the boards on the top floor

Any help or advice would be greatly appreciated.

G'day.
Check the cover width of your existing floor boards.
Chances are that they are not 80mm.

All T&G flooring is or should be kiln dried.
Nobody that I know of profiles green boards.
