Sydney's job seekers will find the most lucrative pay packets in the central business district but the salaries on offer around the high-tech hub of Macquarie Park are not far behind.

The average salary for jobs being advertised in the CBD this month is $90,470, analysis by job search engine Adzuna shows. Next-best was the northern suburbs region - which takes in Macquarie Park and Ryde - with an average of $81,650. The city's lowest average salary for advertised jobs ($67,760) was in the southern Sydney region which includes Hurstville, Rockdale and Sutherland Shire.

The annual full-time salary for vacancies across Greater Sydney last month was $89,636, up 4 per cent on a year earlier and the highest of all the state capitals.

Raife Watson, the chief executive of Adzuna Australia, attributed the increase to a high proportion of vacancies in the city's finance industry.
