The purpose of the instrument is to list the occupations for the MLTSSL. 

The occupation allocations are based on labour market advice from the Department of Jobs and Small Business.

The following eight occupations are added to the MLTSSL: i. arts administrator or manager (ANZSCO code 139911); ii. dancer or choreographer (ANZSCO code 211112); iii. music director (ANZSCO code 211212); iv. artistic director (ANZSCO code 212111); v. telecommunications network planner (ANZSCO code 313213); vi. pressure welder (ANZSCO code 322312); vii. tennis coach (ANZSCO code 452316); and viii. footballer (ANZSCO code 452411). 

The instrument also specifies two new inapplicability conditions. They are as follows: a. the instrument imposes a new inapplicability condition (24) for the occupations of general practitioner (ANZSCO code 253111), medical practitioners (nec) (ANZSCO code 253999) and resident medical officer (ANZSCO code 253112) (medical practitioner occupations).
