The pixel values are scaled reflectance, as 16-bit integers. 
To retrieve physical reflectance values, the pixel values should be multiplied by 0.0001.

The standard form of the file naming convention is:

<satellite category code>
<instrument code>
<product code>
_<where>
_<when>
_<processing stage code>
_<additional dataset specific tags>

For this dataset are (bar-separated):

Data Naming Element | Possible Code(s) | Descriptor Standard Elements
satellite category | cv | Sentinel-2 - all possible
instrument | ms | multispectral
product | re | reflective
where | qld,nsw,vic,tas,nt | state	
when  | myyyymmyyyymm  | season start date (1st day of month) and season end date (last day of month)
processing stage | abm | seasonal surface reflectance
data projection | a2 | Australian Albers Equal Area (EPSG:3577)
