It is the first time Toyota has achieved the quinella by having the two best-selling vehicles in the country in one month.
Toyota's HiLux two and four-wheel-drive ute range sold 3814 units last month, just beating its Corolla stablemate, which sold 3722 units, and the Adelaide-built Holden Commodore, which finished the month with 3324 sales.
New vehicle sales remain ahead of 2007's record pace, but the large car market continues to suffer in favour of small cars and sports utility vehicles.
The automotive industry's VFACTS sales figures, released recently, showed passenger car sales slipped slightly behind the 2007 year-to-date tally, while SUV sales continued to improve across the board.
Light, small and medium car sales continued to grow compared to 2007, but the larger end of the passenger car market continued to decline.
Toyota's Aurion has also come close to beating the superseded BF Ford Falcon, falling just 32 sales short - but Ford's new FG Falcon goes on sale this month.
