Query: A Southern sky search for repeating Fast Radio Bursts using the
  Australian SKA Pathfinder   We have conducted a search for bright repeating Fast Radio Bursts in our
nearby Universe with the Australian Square Kilometer Array Pathfinder (ASKAP)
in single-dish mode. We used eight ASKAP 12-m dishes, each equipped with a
Chequerboard Phased Array Feed forming 36 beams on the sky, to survey
$\sim$30,000 deg$^{2}$ of the southern sky ($-90^{\circ} < \delta <
+30^{\circ}$) in 158 antenna days. The fluence limit of the survey is 22 Jyms.
We report the detection of FRB 180515 in our survey. We found no repeating FRBs
in a total mean observation of 3hrs per pointing divided into one-hour
intervals, which were separated in time ranging between a day to a month. Using
our non-detection, we exclude the presence of a repeating FRB similar to FRB
121102 closer than $z=0.004$ in the survey area --- a volume of at least $9.4
\times 10^4$Mpc$^3$ --- at 95% confidence.
