She wanted to warn ex-staff and children that they also were exposed to deadly asbestos in 1983.
The teacher worked at Shailer Park Pre-School from 1981 to 2006.
She was diagnosed with advanced mesothelioma, an inoperable terminal condition, in January 2010.
She was told she had a limited life expectancy.
She has lodged a workers' compensation claim and in November 2010 she filed a personal injuries damages claim for $765,540 in the Supreme Court in Brisbane.
Trent Johnson, an associate of law firm Maurice Blackburn is urging teachers and all other staff who attended the pre-school in 1983 to consider having health checks.
Mr Johnson said Queensland Government documents confirmed the presence of asbestos within the original 1982 pre-school building and in extensions the following year.
The woman's claim says that she, her co-workers, parents and students inhaled asbestos dust, fibres and particles.
"Normal classes were conducted while the pre-school extensions were under construction and everyone who was at the site during the building works in early to mid-1983 would have been exposed to the asbestos dust," Mr Johnson said.
Mesothelioma and asbestosis can take 10 to 50 years to develop.
