Catchers are made of HDPE [High Density Polythene], and welding rods are available through engineering/bearing trade suppliers, if you don't have an old catcher to cannibalise.

Edit: and I see Bunnings now stock them; https://www.bunnings.com.au/tradeflame-polyethylene-plastic-welding-rods_p5910356
