If it was packaged previously you got the deduction from taxable pay last year so from a salary sacrifice there is nothing happening at the moment.
If you are "depreciating" the FBT exempt asset that you received from your employer (i.e. the QP membership over 10 years and the laptop in line with the ATO guidelines) then this is not affected.
The way it works is that if your employer gives you a non-cash benefit in kind (such a case of grange, diamonds, gold bullion) you as an individual are not taxed on the asset but instead your employer pays the fringe benefit tax on it. All that has changed is that the government has now said that a number of items which did not attract FBT now do so.
If anything the historic term of "salary sacrifice" in itself indicated that the scheme was not quite operating as the ATO would have wanted. I think the idea is that if you are given something that will help you do your job then you and your employer should not pay tax on that. However the way the schemes have been run is as a way to get more cash into people's pockets - and in the main not through the provision of assets that help you do your job.
We used to have lots of schemes like this to avoid national insurance contributions in UK - people even paid in poison (???) to a GBP value equivalent to their salary that we then bought off them and traded. Those schemes got dropped when the govt got wise...
