I've got several clumps of them growing and occasionally stems/trunks get broken by falling branches or fronds. Those stems never re-sprout except from the base. They're a clumping palm but are fairly slow growing. Eventually they will be tall. I've never tried cutting out stems to force new growth but it should work okay if the plant is healthy. When you say "they'd like it to look healthier", does it look sickly, or are they just concerned about it looking spindly? Because, spindly is what that species looks like, it's not a question of health.

It's normal for older leaves to yellow and die off, as long as you're getting new ones at the top. When it comes to watering it's best not to go by regular intervals. As weather fluctuates water evaporation rates change as does plant up take of water. You need to check moisture in the soil and water as needed. It's best to have fast draining potting soil as then it's more difficult to actually over water the plant. You can also give it an occasional good flush with water to prevent build up of excess mineral salts from fertiliser. I'd use the slow release fertiliser when repotting, they don't need a lot. With the vagueries of Melbourne weather I'd be careful about leaving it out all the time this time of year. (I'm in Darwin but know how it can be down there). The Bamboo Palm is Chamaedorea seifrizii and it's a multi trunked palm, so it will keep growing more trunks/stems (I have some with stems over 4 metres long). The Parlour Palm is Chamaedorea elegans which is a single trunked palm. So you have multiple plants in that pot. Due to competition from so many of them growing crowded together you'll have to expect some of the weaker ones to die off. That's normal. Otherwise, they're a good indoor palm and fairly slow growing. They can get up to a couple of metres tall, but you won't have to worry about that for quite a while.

Sorry for the slow reply. I accidentally let it get burnt leaves from direct sun light, and i also think i either over watered it or it needed better soil drainage because it held water in the soil a long time. its slowly died off and i have removed all the dead bits untill it is what it is now. i removed a whole lot of dead roots aswell. Its held that one green stem for a long time so i was wondering if i put it into a smaller pot of soil could i slowly revive it or is it to far gone?

Thanks for the response! I mean, I think they were dead. If there was only one or two dried and shriveled leaves I would just cut those. But there were quite a few branches where ever single one was brown and dry and crispy. I wonder why it’s doing this. Could it be the moving stress? it’s by a south facing window with filtered light through the blinds, a humidifier running 24/7 right next to it, only water with filtered water when the top few inches of soil are dry. And I used a cactus / citrus / palm organic mix and the pot has a drainage hole. These guys are supposed to be hardy, if I can’t manage him I don’t think I can manage any plants :( also, just out of curiosity, does the after picture look over-pruned or cleaned up? I feel like it’s a fine line.
