Update: On 9 May 2018 we released the GALAH survey DR2.1. This contains a fix to three columns related to radial velocities, populates the gaia_dr2_id column, and adds a collection of high-SNR median spectra. See the changelog for more details.

The catalogue is accessible through:

• The query services on the AAO Data Central webpage
• TAP via https://datacentral.org.au/vo/tap
• Direct download (the median spectra are also downloadable here)
