Get him checked out. There may be an issue with his ears, he might not be hearing you properly which could be the issue. This happened to my nephew. Keep reading to him regularly. Try to get books that he can sound out the words, but are fun to read. Persistence is the key here, it’s hard but no doubt he will talk when he is ready.

Read, sing, talk to him about what you are doing while you do it and be patient you will get there.

I agree check hearing just to rule that out. Sounds like you’re doing a great job with him. Have you ever looked into ‘baby sign language’? There’s some good Australian sights. He may not pick it up, but if he does it could be helpful in bridging the communication gap. I’ve started with my 9 month old, he hadn’t picked it up but i just do the sign as I say words. Like ‘more’? As I tap my chest, or ‘all done’ as I shake my hands. After doing that for a while I now do it and take his hands and guide him to do it.
Just to start getting used to toilet training- sit him on the potty for an episode of pepper pig before getting into the bath or something. Starts to normalise toilets. And if he does do any wee it pop give him a little treat like a lolly or sultana:). That’s pretty normal to not be interested yet, but I bet you may be keen to get one out of nappies:)
All the best!

My friends sons did the same thing and now they can not shut them up. One started to talk but very loud… Have is hearing tested for sure though as one of my friends son needed grommets after having a infection some time ago. Both toilet trained at the age of 3-4 years. All children are different just be patient.

Check this speaking issue with the doc. My 2 year old boy is noisy. He doesn’t want to go to the potty either yet but i am willing to give him more time to come around to the idea

Sounds like my sons. My eldest who is now six had selective mutism and didnt talk much until he started school and this was with everything from speech theropy to seeing physicologist etc. He also had a lot of anger issues as he couldnt express himself which didnt help at all. My daughter could hold a conversation from the age of two no worries. So with my youngest who is the same age as your son we decided to get help earlier than we did with my eldest he now is getting speech theropy. Which relly means we are been shown the tools to help him develop his words and he is now starting to talk a little more and isnt as angry as my oldest was at the same age. As we are usuing his signs. When he is thirsty he goes to the fridge and knocks on the door and we sayOh do you want a drink, Yes? After a while he started to say yes and it all went from there. Every chid is different and with the right help they will start talking in their own time. Next time you are at the doctors or health nurse tell them you are worried and they might refer you to someone who can help.
