1. Does that job which i am currently doing, must need to be advertised on seek or somewhere? as i went through a recruitment company and I guess I was the only one they forwarded because I was the only one matching employer's requirements.
I assume you are currently on a work visa, and preparing to apply for Residence under SMC.
There is no requirement for a labour market test for that.
2. where can i find job descriptions to compare with anzsco codes. my title is most closely related to 224999(procurement specialist) but i can't find job description for this role anywhere.
I'm looking here.

That gives you the title page for the whole group including your chosen role, which shows the Indicative Skill Level and a 'Tasks include' list.
