How do I seal gaps on interior raw brick walls?

Hello from Australia
I have raw brick walls inside of my house, so in each room there are 2-3 plastered walls and one raw brick wall. I have attached neighbours on both sides. I need to know how to deal up the gaps in between the bricks and the plastered walls and built in robes. Bugs walk right through the gaps and I can clearly hear the people next door, even in the bathroom. I am wondering if there is some type of putty to fill the gaps or clear veneer that I can cover the wall with please? 
Here in Canada, we have some plastic trims available to clean up the edges that contact the brick wall. The term for the one I am thinking of is called "tear away." It glues on with the manufacturers adhesive/spray. Adhesive is applied to both surfaces and then stapled on to the drywall. It is then mudded over to conceal the trim. When finished, part of the trim is torn away. This part of the trim prevented the mud from going on the brick. always a good idea to tape up the brick until you're finished anyhow. Apply primer and paint and you're done. Hope you can find this trim in your country.
