Cabin luggage on Australian domestic flights

I am traveling to Australia in 2 weeks. I will be taking multiple domestic flights to go from one city to another in Australia. I found that in all of my domestic flights, I have to pay extra for check-in luggage. So, what I was thinking to do is take 2 bags with me of the following types:

Laptop bag.
Trolley bag of 55 cm (example: here).

Is it okay to carry 2 cabin bags on domestic flights? I live in the United States and I know here it is allowed in almost all the flights. But I am not sure about Australia. I know it might depend on flights too. So, I am listed down the flights that I am using in Australia over here as follows:

Jetstar
TigerAir

Also, does someone check the weight of the bags? I know the maximum allowance is written as 7 kg for cabin luggage, but I have never seen anyone checking this. They normally just check the dimensions at most. And say, if it gets checked, what kind of fine most airlines impose and then does it go as the check-in luggage or cabin luggage?
