Unauthorised disclosure of information about a notice (or gained from a notice) is punishable with 5 years imprisonment -- which means that if you're suspected of being a whistleblower they can use this new legislation against you too (anything punishable with over 3 years imprisonment can be investigated in this fashion).

I wouldn't risk it. There are ways to legally provide aggregated information about the number of notices received in a 6-month period.

Also, talk to your representative and explain your concerns and push for it to be scrapped (though when I talked to the Labor senators' staffers they brushed me off and said that I wasn't interested in being informed when I disagreed with their party line). Federal elections are coming up, they're more likely to at least pretend to listen to you.
