The news follows a 2012 Sydney show that saw a number of key brands absent, including top prestige marques BMW and Audi, along with Ferrari, Rolls-Royce, Maserati, Chrysler, Jeep and MINI.
Tight marketing budgets and, clearly, growing doubt among vehicle manufacturers as to the marketing value of motor shows to their brands, would likely have seen a similar number of 'no-shows' in Melbourne this year.
"We have made the decision to not proceed with this year's Show based on a consensus view of the Automotive Industry to focus limited marketing budgets in 2013 on firm specific activities rather than an industry based Motor Show," International Motor Show Director Russ Tyrie said.
Future shows could also be in doubt, with the AIMS Joint Venture confirming today that it expects a pause in planning activities as options are considered.
This will be a blow to the joint venture partners.
Having agreed, after pressure from manufacturers and importers, to share the show between Melbourne and Sydney with just one annual Australian International Motor Show, they would not have so soon expected the ship to show serious signs of sinking.
Motor shows have become an expensive business for vehicle manufacturers, and especially so in Australia's relatively small vehicle market which carries such a proliferation of brands and models.
Not helping the cause has been the trending down of public attendance numbers over the past decade.
Tyrie said that decisions on future events, including 2014 (whether in Sydney or in Melbourne), will be based on market research and consultation with the industry.
"In not proceeding with the Show in 2013, Australia is following a global trend that has been apparent for several years, where cities do not always have a Motor Show," he said.
"This trend is evident in the recent suspension of Motor Shows in London, Zagreb and Amsterdam."
