Hey ScottyDuck..congratulations to you and TeniBear!

Have a look into Specsavers..they employ alot of casuals and pay really well. Have a look at the website. Most Specsavers are franchised so the store itself does the hiring.
They employ all sorts...could be just to stand out the front of the shop and hand out spec clothes or give aways at train stations or work in the store itself.
They will also train you and if you work at Macca's that usually looks good on your resume.
