I found the answer after reading through some of the M2 forums and it turns out that the Aus version does have an opf. Basically all M135i in Aus are euro 6 compliant ☹
It presents an issue for me because I cannot go to my local exhaust shop and delete the opf without a tune done to eliminate running issues like error codes and/or the car going into limp mode.
There are two options so far that I know of that can get rid of the error codes generated when the sensors detect a difference in exhaust flow (due to the removal of opf)
1) a tune or
2) installing a manhart chip that disables the 02 sensor
So until I find a tuner or buy the chip, I will have to settle for an axle back exhaust.
I found this website WebETK that gives you more info on the opf's and other car parts in general. You will need to enter your VIN details to bring up your vehicle. S1DEA is the OPF code.
If anyone has any info on how to get more sound, please share!
I took a pic of what I think is the opf and resonator? Not sure yet

I've done some research into this as well as I am curious. Australia does not have OPF installed for these cars. S1DEA is not optioned.
Jumping under the car, mine looks exactly like yours and had the silencer had part # 8619455 and the shorter cylinder was #82192830 which is a catalytic converter.
Took me awhile!
