SEEK s Senior Employment Trends Analyst Leigh Broderick said these seasonal shifts in volume were impacted by holiday periods like Easter and Christmas, as well as the start and end of the financial year. While there are always plenty of roles advertised on SEEK we can see certain times of the year have more opportunities than others, said Mr Broderick, speaking to news.com.au. The start of the calendar year in January and February see a boost in job ads as businesses prepare for the year ahead. There is also a boost in job ads in October and November as businesses prepare for the holiday period.
