We report the results from a survey of the Galactic plane for dispersed single pulses using the Australian SKA Pathfinder ( ASKAP ) .
We searched for rare bright dispersed radio pulses comprising 160 pointings covering 4800 deg ^ { 2 } of the Galactic plane within { | \text { b } | < 7 ^ { \circ } } , each pointing with an exposure time of 10 hours .
We detected one fast radio burst , FRB 180430 , and single pulses from 11 pulsars .
No rotating radio transients were detected .
We detected FRB 180430 in the Galactic plane in the anticentre direction with a fluence of 216 \pm 5 Jy ms a dispersion measure ( DM ) of 264.1 \text { pc } \text { cm } ^ { -3 } .
We estimate the extragalactic DM of the object to be less than 86.7 \text { pc } \text { cm } ^ { -3 } depending on the electron density model .
One model suggests that this FRB may be a giant pulse within our galaxy ; we discuss how this may not correctly represent the line-of-sight DM .
Based on the single detection of FRB 180430 in 3.47 \times 10 ^ { 4 } \deg ^ { 2 } \text { h } we derive a FRB event rate in the Galactic plane at the 20 Jy ms threshold to be in the range 2–140 per sky per day at 95 % confidence .
Despite the necessarily large uncertainties from this single detection , this is consistent with the current ASKAP all-sky detection rate .
