This paper presents optical ($ugri$H$\alpha$)-infrared($JHK$s,3.6--8.0$\mu$m) photometry, and $Gaia$ astrometry of 55 ClassicalT-Tauri stars (CTTS) in the star-forming region Sh 2-012, and it's centralcluster NGC 6383. The sample was identified based on photometric H$\alpha$emission line widths, and has a median age of 2.8$\pm$1.6 Myr, with a massrange between 0.3-1 $M_{\odot}$. 94% of CTTS with near-infrared cross-matchesfall on the near-infrared T-Tauri locus, with all stars having mid-infraredphotometry exhibiting evidence for accreting circumstellar discs. CTTS arefound concentrated around the central cluster NGC 6383, and towards the brightrims located at the edges of Sh 2-012. Stars across the region have similarages, suggestive of a single burst of star formation. Mass accretion rates($\dot{M}_{\textrm{acc}}$) estimated via H$\alpha$ and $u$-band lineintensities show a scatter (0.3 dex) similar to spectroscopic studies,indicating the suitability of H$\alpha$ photometry to estimate$\dot{M}_{\textrm{acc}}$. Examining the variation of $\dot{M}_{\textrm{acc}}$with stellar mass ($M_{\ast}$), we find a smaller intercept in the$\dot{M}_{\textrm{acc}}$-$M_{\ast}$ relation than oft-quoted in the literature,providing evidence to discriminate between competing theories of protoplanetarydisc evolution.
