We have conducted the first parallax and proper motion measurements of 6.7GHz methanol maser emission using the Australian Long Baseline Array (LBA). Theparallax of G339.884$-$1.259 measured from five epochs of observations is0.48$\pm $0.08 mas, corresponding to a distance of $2.1^{+0.4}_{-0.3}$ kpc,placing it in the Scutum spiral arm. This is consistent (within the combineduncertainty) with the kinematic distance estimate for this source at 2.5$\pm$0.5 kpc using the latest Solar and Galactic rotation parameters. We find fromthe Lyman continuum photon flux that the embedded core of the young star is ofspectral type B1, demonstrating that luminous 6.7 GHz methanol masers can beassociated with high-mass stars towards the lower end of the mass range.
