These are yet another river snail style noodles. This particular packet is "crayfish flavoured" and is sold under the brand "Uncle Shaw" manufuctuerd by Guangxi zhongliu food Technology co, LTD. These are made in Liuzhou city.

This brand sells many variations and seems quite popular on youtube. They also have physical stores. Here is a company album.

I got these for $AUD4.00
