Thank you everyone for the replies and feedback, I really appreciate it and now have lots more food for thought! I purchased my BG 2000 from Dinga and was very happy with the service, will see what else they have that might suit.
So it seems the general consensus is a 4-6kg rod would be more appropriate than the 6-15kg and reel anywhere from 2500 to 5000 size. I probably don't go out more than a few times a year if I am lucky, I have a toddler who I've also just introduced to the hobby and enjoyed it immensely (tho, would prefer to stick with beach and not too keen on rock for safety factor).
The Rovex rod I found for $70 so probably stick to the upto ~$100 ball park for suitable rod, I'm not sure I'd get enough use to warrant $200+. As for the reel, my reading so far suggests ~100m is the furthest casting distance from shore, so how much spool capacity is sufficient? 200m, 300m? I am assuming less is best in that no point having a bunch of line that will never get used, but enough that if the fish runs away I don't run out of line?
