(ETA: I am referring to the very first photos on this thread.)

Your first picture looks to me like Acacia. Not sure which one but check out Acacia floribunda.

Second photo - no idea.

Third photo is a lovely thing. Acacia fimbriata??? Baeckea virgata??

Forth one looks like another wattle. Maybe the same as in the first photo.

Fifth and sixth - no idea.

Seventh - maybe the same as the first.

Those fine-leaved shrubs will presumably produce seed. They will be much easier to ID then but might still be difficult as there are about 600 species of wattle. Have you considered waiting for seed and treating that seed with boiling water (for Acacia seed) and sowing them directly?

Baeckea (if it's Baeckea) also grows readily from seed. The seed needs no treatment. Really, the hardest thing is to keep sown seed moist while germination takes place. Also there is the need to protect from rabbits because they will chomp young plants off with their teeth. (They like to keep a view.) If using a tree guard, it is good to leave a small gap at the bottom instead of having the plastic hard up against the soil because little birds are attracted to the insides of tree guards due to insects that might gather there due to the extra warmth. If there is no small space to get out under the plastic, the birds can die, as it is difficult for them to take off in a normal fashion from such cramped quarters.
