We report on time-resolved photometry of the 2005 July superoutburst of the dwarf nova , 2QZ J021927.9-304545 .
The resultant light curves showed conspicuous superhumps with a period of 0.081113 ( 19 ) days , confirming the SU UMa nature of the object .
Although we missed the maximum phase of the outburst , the amplitude of the superoutburst well exceeded 5 mag .
This value is slightly larger than that of typical SU UMa-type dwarf novae .
The superhump period decreased as time elapsed , as can be seen in most SU UMa-type dwarf novae .
Based on the archive of ASAS-3 , the recurrence time of a superoutburst of the variable turned out to be about 400 days .
This value is typical of well known SU UMa stars .
The distance to this system was roughly estimated as 370 ( +20 , -60 ) pc using an empirical relation .
