Oh dear - how good that you had your lovely holiday before diagnosis, @Caz1 - and SO sorry to see you here! But you're in the right spot for asking questions & getting honest advice from those who've been before you!
Melbourne has a HEAP of specialise BC support areas - I am sure our members there will jump on & point you to them.
Great that you have strong family support - it all helps. All the best with your remaining chemo & surgery et al ....
You should be able to access a dietician re your swallowing problem - I hope you get some assistance quickly! I didn't have chemo, so didn't experience that - but my husband lost most of his stomach to cancer, so was on a special 'high protein/sloppy' diet for ages, til he could tolerate 'normal food' and now he eats whatever I do! Not bad for an old fella (he was over 70 when diagnosed!) He also got back to international Triathlon Competition as well - so pretty amazing, all round!
Take care, all the best for your ongoing treatment xx
